According to Research gate
The research was conducted by some scientists, published in a journal, and then uploaded to research gate. So, research gate itself cannot be the reference, but the scientist. It is preferable to dig for the source of information when making scientific claims.
The names of the authors are there on research gate, and even the DOI.
Okay. I'll edit it and add their specific names. thank you for drawing it to my attention
